1. Super fast.
2. Image search is far superior to Google's.
3. Travel search is great. Try "deals to hawaii".
4. I like the name. Easy to remember and only 4 letters.
5. Weather searches work great.
6. I like the related searches and search history on the left.
7. I like the wikipedia integration.
1. Similar quality of results.
2. Superior image search. Actually, I think Google's image search is a result of them being on top for so long, it's been the same for years with little improvement. I mean, just look at Bing's.
3. Better video search. I love the hover-preview feature. I can see Google implementing it next year after some other mainstream sites implement it and it's no longer a "Bing thing."
4. Slightly cleaner interface. Let me show you: http://r.im/1rf7 http://r.im/1rf8 Bing has a line-height of 130% which makes it a little more readable in my opinion. Sure it has more clutter in some areas, but the search results are cleaner and that's what matters to me when I'm scanning through them.
I don't use maps, travel, health, etc., so I can't comment on them, but so far I'm very pleased with the results. I didn't think Microsoft could pull it off and they did.

(looks like the May 27 version)
The quality of normal results (the only ones I can get) is bellow Google.
From the US you get powerset-like answers to questions like "president of x".
